We're only just reaching the end of the first working week of '09 (hurrah- it's Friday!) but our favourite fashion designers have given us the perfect excuse to blow the New Year's diet already...The Berkeley Hotel's famous fashion Pret-a-Portea - featuring cakes and biscuits in the top bags, dresses and shoes from the new season collections - has gone mobile with the new Pret Vepsa service - and we're loving it! Just order your fashionista fancies from the hotel and hey presto - they'll be whizzed over on a pink and pistachio Vespa right to your door. We've swooned over the AW08 Prada lace dark chocolate creme, the Christian Louboutin 'Pigalle' green glitter biscuit and the Alexander McQueen fromage blanc chiffon dress with raspberry meringue - and it looks like we're not the only ones swooning into our biscuit tins. Kate Moss, Naomi Campbell and Gwynnie are all fans of the fashion treats and champagne tea - now we've spotted Alice Temperley, Philip Treacy and Anya Hindmarch munching on the biscuit versions of their own designs! With chic treats like this available to your door, we're suddenly wondering why we bothered about that diet anyway... £25 for 10 biscuits, (including delivery for SW1).Prêt-à-Portea is served in The Caramel Room at The Berkeley from 1-6pm everyday priced at £35.00 per person. (£43 including a glass of Laurent Perrier champagne, or alternatively for the fashion conscious, £49.00 per person including a glass of couture champagne).To make a reservation for Prêt-à-Portea or order Prêt biscuits to be delivered on your doorstep call 020 7235 6000.
